Application filed (ictober 24, 1916. Serial No; 127,368.

To all whom it may concern: Be itknown that I, JOHN EsTocK, a c1t1- zenof the United States, residing at Yon- 'kers, in the county ofWestchester and State of New York, have invented certain new and usefulImprovements in Mechanical Move-- ments; and I do hereby declare thefollowing to be 'a full, clear, and exact descrlptlon of the invention,such as will enable others skilled in the art to which it appertains tomake and use thesame. This invention relates to new and useful 1improvements in mechanical movements and tension on the driving chain.

the principal object of the invention is to provide a device forincreasing power.

Another object of the invention is to' provide a device consisting of afulcrumed lever, the long end of which is driven by a suitable motor orother power generating device which lever has its short end connected toa suitabl connecting rod and crank for turninga shaft to operate a drivewheel, which may be used for turning varlous machines. r a

A still further object of the invention is to provide a novel means foradjusting the A still further object of the invention is to provide adevice having a balanced lever so that the power wasted in moving thelever will be minimized. With these and other objects in view theinvention consists in the novel combination and arrangement of partswhich will be fully set forth in the following specificationand.accompanying drawings, in wh1ch:

Figure 1 is a side view in elevation of a power increasing deviceconstructed in accordance with this invention.

Fig. 2-is a top plan view of Fig. 1. Fig. 3 is an end view of thedevice. Fig. 4 is an end view fromthe opposite end of Fig. 3.

Fig. 5 is a vertical sectional view on line H of Fig. 3. I

Fig. 6 is a horizontal sectional view on an enlarged. scale taken online 66 of Fig. 3.

Fig. 7 is an enlarged fragmentary detail sectional view of a pair of thestandards showing the method of adjusting the bearm s.

%ig. 8 is an enlarged fragmentary sec tional view of one end of thelever showing the b alancing weight and method of securmg the same inplace, and

Fig. 9 is a transverse sectional view on line 9+9 of Fig. 8.

Referring to the drawings, the numeral 1- designates as an entirety thebase of the device comprising a pair of parallel side bars 2 held inspaced parallel relation by transversely extending end bars 3. Suitableintermediate bars 4 are positioned between the side bars 2 and near theend bars 3 in spaced parallel relation and extending. upwardly from thetransverse bars 4: are standards 5 which are held in spaced parallelrelation by suitable longitudinally and transversely extending bars 6and 7 respectively. These bars 6 and 7 are arranged adjacent the upperends of the standards 5 as clearly shown in the drawings. Upon referenceto Fig. 2 it will be seen that the standard to the right is supported onextensions on the bars iwhich are braced by suitable reinforcingbrackets 8 illustrated in the drawings. Extending upwardly from the bar3 are suitable standends 9 connected at their upper ends by atransversely extending bar 10 and a suitable connecting bar 11 extendsbetween the standards 9 and 5 as shown in Fig. 5.

Extending upwardly from the side bars 2 near the end of the machineopposite that to which the bars 4 are connected are suitable standards12 and intermediate the ends of said side bars are standards 13. Thesestandards are arranged in pairs and connected by transversely extendingbars 14: and longitudinally extending bars 15. The bars 15 are recessesas at 16 and a suitable cap 17 is fitted over each of said bars andprovided with recesses 18 which a-line with the re:

cesses 16 and form bearing openings in which the drive shaft of thedevice is mounted. Suitable braces 17 are connected to the standards 12and 13 intermediate their upper and lower ends as clearly shown in Fig.'1. Extending upwardly from the side bar 2 on the right are standards 19supporting at their upper endsa suitable transversely extending bar 20which is provided with a central recess 21 and has a cap 22 fittingthereover which is recessed as at 23 to form a bearing in which thefulcrum pin is mounted. This fulcrum pin supports the lever in operativeposition as clearly shown in the drawings. Suitable standards 22 extendupwardly;;from the base intermediate the ends ofthe bars and serve tobrace the same centrally in order from sagging. v

Mounted in the openings formed by the recesses 17 and 18 is the maindrive shaft 24 carryingat its outer end the fly wheel 25 to prevent themand intermediate its ends with a belt Wheel 26. This, belt wheel ismounted between the standards 22 as shown in Fig. 4. A crank 27 isconnected to the inner end of said shaft and has rotatably connectedthereto a connecting-rod 28 which is pivoted at 29 to the leverdesignated generally by the nu meral 30. The lever 30 above referred tocomprises an arm 31 provided with a fulcrum pin 32 which is rotatablymounted in the recesses 21 and 23 and this arm is provided at the endnearest the fulcrum pin with a'recess or pocket 33 for the reception ofsuitable weights 34. These weights are retained in place by a strap 35which fits over the end of the lever as clearly shown in in suitablejournal bearings ,50 mounted be-v ournals for the shafts 41 of the drivechain;

Suitable wedges 42 are driven into the recesses 37 beneath the guides 38and it will thus be seen that the distance between the sprocket may bevaried in order to vary th tension on the chain.

The shafts 41 are mounted between their respective pairs of standards 5and ,the inner ends of said shafts are provided with sprockets 42 overwhich the chains 43 pass. The sprockets 42 are preferably positionednear the upper ends of the standards while suitable sprockets 44 aremounted in similar bearings and on similar shafts near the lower ends ofthe standards. The shafts of the sprockets 44 are designated bythe.numeral 45 and carry suitable drive sprockets46 over which thedrrvdchains' 47' pass. Thesedrive.

chains are driy en by thelarge sprockets 48 mounted on the shaft 49which is supported tween the standards 9 and 5. I

Extending between the chains 43 and carried therewith is a suitableconnecting pin 51 which extends through the slot 36 in the lever 30 sothat upon movement of the chain the lever will be oscillated.

It will be apparent from the foregoing that in use the device is drivenby connecting a suitable motor or engine to the belt wheel.

52 thuscausing the shaft 49 to revolve and I drive the sprockets 48 thusdriving the sprocket 46 through the medium of the chains 47 which inturn drive the shafts 45 and the chains 43. Assuming that theconnectingpin 51 is carried by the runs of-the chain to the right in Fig. 5 andthat the wheel 48 is operating in a clockwise direction, it will be seenthat the lever 30 will move downwardly until the pin reaches itslowermost distance of travel whereupon the same will start upwardly onthe opposite run of the chain thus causing the lever 30 to oscillate.The oscillatory movement of the lever will cause the shaft 24 to revolvethus operating the" fly wheel 25 and the drive wheel 26. I

While in the foregoing there has been shown and described the preferred.embodie ment of this invention, it is to be understood that suchchanges may be made in the combination and arrangement of parts as willfall within the spirit and scope of the invention as claimed.
